Background and aims: This study examines gender-specific behavioral correlates of depressive symptoms using a secondary data analysis of a cross-sectional, population-based sample of older unlike-sex twins.

Methods: Unlike-sex twins aged 69–88 were identified through a national Swedish registry and sent a survey about health, including depressive symptoms (CES-D) and the frequency of engaging in physical, social and mental activities. A total of 605 complete twin pairs responded.

Results: Depressive symptom scores were associated with frequency of engagement in physical and mental activities, but only in men. No statistically significant associations with depressive symptom scores for any of the three types of activities were found in women.

Conclusions: The results suggest that engaging in physical and mental activities may protect older men from developing depressive symptoms, but longitudinal data are needed to offer more conclusive findings on the role that physical, mental, and social activities play in the maintenance of psychological health in older men and women.

Background and aims: Existing information about institutionalization of elderly individuals is mainly based on cross-sectional data and does not address the cumulative risk of institutionalization. The purpose of the present study was to analyze longitudinal data prospectively and estimate the risk of placement in an elder care institution for individuals aged 70 years or older. Methods: The study was based on a longitudinal investigation (the H70 study) of a random sample of 70-year-olds living in Gothenburg, Sweden, in 1971. Individuals were followed from age 70-100 years. Three different analyses were performed: a descriptive prospective analysis, cross-sectional analyses at ages 70, 79 and 85 years, and a longitudinal analysis of predictors for institutionalization. Results: The prospective analysis indicated that 50% of the individuals eventually moved to an elder care institution. Significantly more women than men were institutionalized, although for women the move occurred later in life. Cross-sectional analyses demonstrated that various factors were important to institutionalization at different ages. The Cox regression model with time-varying covariates indicated that gender, socio-economic situation, marital status, number of symptoms, having children living nearby, and activities in daily life were related to institutionalization. Conclusions: The proportion of elderly persons relocating to institutions was significantly higher than that generally found in cross-sectional studies. It was possible to identify variables that predict institutionalization during a subsequent 30-year period, but different analyses revealed different effects from the factors evaluated.

Background and aims: It is known that physical performance declines with age in general, however there remains much to be understood in terms of age-related differences amongst older adults across a variety of physical components (such as speed, strength and balance), and particularly in terms of the role played by multimorbidity of chronic diseases. We aimed to detect the age-related differences across four components of physical performance and to explore to what extent chronic diseases and multimorbidity may explain such differences. Methods: We analyzed cross-sectional data from a population-based sample of 3323 people, aged 60 years and older from the SNAC-K study, Stockholm, Sweden. Physical performance was assessed by trained nurses using several tests (grip strength, walking speed, balance and chair stands). Clinical diagnoses were made by the examining physician based on clinical history and examination. Results: Censored normal regression analyses showed that the 72- 90+ year-old persons had 17-40% worse grip strength, 44-86% worse balance, 30-86% worse chair stand score, and 21-59% worse walking speed, compared with the 60-66 year-old persons. Chronic diseases were strongly associated with physical impairment, and this association was particularly strong among the younger men. However, chronic diseases explained only some of the age-related differences in physical performance. When controlling for chronic diseases in the analyses, the age-related differences in physical performance changed 1-11 percent. Conclusion: In spite of the strong association between multimorbidity and physical impairment, chronic morbidities explained only a small part of the age-related differences in physical performance.

Background: Falls and related injuries are common among older people, and several drug classes are considered to increase fall risk.

Aims: This study aimed to investigate the association between the use of certain drug classes and falls in older nursing home residents in Sweden, and relate these to different age groups.

Methods: Information on falls that occurred in the previous year and regular use of possible fall risk drugs including non-benzodiazepine hypnotics (zopiclone and zolpidem) was collected from 331 nursing home residents during 2008–2011. Over the following 6 months, the occurrence of serious falls, requiring a physician visit or hospital care, was registered. Association between serious falls and drug use was compared between an older (≥ 85 years) and a younger group.

Results: An increased fall risk (Downton Fall Risk Index ≥ 3) was found in 93% of the study subjects (aged 65–101 years). Baseline data indicated an association between falls that occurred in the previous year and regular use of non-benzodiazepine hypnotics (p = 0.005), but not with the other studied drug classes. During the following 6 months, an association between use of non-benzodiazepine hypnotics and serious falls in the older group (p = 0.017, odds ratio 4.311) was found. No association was found between the other studied drug classes and serious falls.

Discussion: These results indicate an association between falls and the use of non-benzodiazepine hypnotics, compounds that previously have been considered generally well-tolerated in older people.

Conclusions: Caution is advocated when using non-benzodiazepine hypnotics regularly in older people living in nursing homes.
